Teen Mom 2 star Jenelle Evans has a lot of explaining to do if this turns out to be the truth!

Some new texts from Jenelle have come to light that seem to prove the reality star has been toking massive amounts of marijuana while she's been pregnant, and it doesn't seem like she's going to stop her weed habit anytime soon!

Jenelle was recently in Los Angeles, and tried to make plans with her friend to get high and drive along the strip before her flight home. Here's what one text from February 10th supposedly said:

“We can smoke and chill on a huge f**king blunt lol"

And then on February 9th she wrote:

“Let’s drive and smoke I don’t want to be here. Just down the strip and back or something I need to get away.”

One close person to the pregnant lady claims that the reason Jenelle is getting high so much is because of the morning sickness she's been experiencing. The source said:

“She told me that if she doesn’t have weed she will throw up due to her pregnancy. So she always has a lot of weed on her at a time. When Jenelle runs out of weed she will drive from her house in Myrtle Beach, South Carolina to Brunswick County in North Carolina, which is a 2-hour round trip to buy $120 worth of weed."

And although we thought maybe her boyfriend Nathan Griffith was a good influence on her, this source claims appearances are deceiving! Apparently he's been peer pressuring her to drink with him! The source said:

"I have been over at her house before when Nathan asked Jenelle to take fireball shots with her. Jenelle smelled it and claimed she almost threw up because she is pregnant. Nathan told her a couple shots wouldn’t affect the baby, but calm Jenelle’s nerves.”

WOW!!! If this is true, then…oh man, we're speechless! Jenelle Evans has got to know this stuff can be potentially super harmful to her unborn child, right???

Jenelle and Nathan apparently have been fighting a lot, too. And when they do - he brings up Jenelle's ex Courtland Rogers and her history with harder drugs.

Here's what one text from Jenelle revealed:

“He said maybe I can get back with my husband and shoot up heroin again. And I’m sitting here silent as usual.”

Eek! Obviously if Jenelle is having trouble with her baby daddy, that can lead to depression and the urge to get high on weed, but really it's not okay for her to do that!

Even if she has smoked, that can't be changed at this point. BUT if she stops all that nonsense now - it will be the best decision she can possibly make!

Unreal. I feel so bad for this baby. It's going to be so brain damaged and jenelle doesn't give a shit about her son Jace or her unborn child. She needs to become sterile so she can't harm any more lives!

She should not be allowed to breed! She was a dead beat mother once and she's an even worse mother again. If this is true, child services should take the baby away straight after it's born. She can't look after it in utero, she won't be able to after. Selfish, selfish girl!!!

Omg y are u piping out kids and can't even take care of yourself y can u just think about jace and stop jumping from relationship to relationship cuz your makin yourself look bad u need to get your life together your a low life beat mom your ignorant

Jenelle beds boy after man after boy after man, does her body ever go without some full-on jerk all over her? She is mentally ill, she doesn't take her meds but she takes every other drug she can get her hands on. I don't know why anyone is surprised that this new guy is just more of the same, no sane, decent man would touch her with a ten-foot pole. And her mom, good gawd the whole family is mentally ill. Jace or any other kids she has, do not have a chance in life.
